WebAug 31, 2024 · 1 Answer Sorted by: 1 It all results from lil' Fermat, but could be explained in a shorter way: Remember that Fermat asserts that, for any a, not divisible by p (a prime), we have a p − 1 ≡ 1 mod p, which simply means that the remainder of the division by p is 1. Now a p − 1 = a ⋅ a p − 2 = a p − 2 ⋅ a ≡ 1 mod p. WebCryptoHack – General challenges General This category tests your skills in fundamental areas for understanding modern cryptography.
